A slang Belfast term, meaning the act in which an massively inebricated person displays their penis to friends or family members. Their reason for doing so is never obvious.

Supposedly linked to a famous event involving an inebriated person by the name of McKeown. After waking the family he shouted "its ok. Your a McKeown, shes a McKeown and this penis pulled out is a McKeown". (Thou this is possibly a weak urban legend)
God, im so wasted im worried I will end up McKeowning later on.
